Hi.

As far as I am not an Erlang expert, some ideas discussed here are not peculiar to Erlang.

Alphabetical order may or may not help. Modular code produces modules with small number of objects that can be efficiently visually navigated. The relationship between how efficiently and the number of objects, AFAIK, is undetermined.

Some convention to ease navigation accross different modules would be more sensible and worthwhile, IMVVVHO, of course.

Obviousness is a function of familiarity. I often see this in software documentation that is obvious for the author. :-) 

Style is not about aesthetics. It is about discipline. And discipline is about standards. Navigating a module with a previously known internal organization is far more efficient. Several languages have (or had) structural rules for their codings. 

Some tags and comments work as markups that can ease learning and navigating by working as coding standards. Besides, disk space is not expensive today. :-)  Not to mention that such standard markups will be essential for future implementation of cross module indexing systems and other indexing mechanisms.

My 2 cents.
